1 mole of a gas occupies 22.4 L at ________

Answers

Answer 1

Answer: At STP, one mole (6.02 × 1023 representative particles) of any gas occupies a volume of 22.4 L (Figure below). A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm).

Explanation:

That the answer

Answer 2

1 mole of a gas occupies 22.4 L at (0°C and 1 atm). It is the standard temperature and pressure.

What is Avogadro's hypothesis?

Avogadro's hypothesis says that all gases have an equal number of particles at the same temperature and pressure.

The empty space between the particles makes up the majority of a gas's overall volume.

Due to this, the size of the particles themselves is nearly insignificant.

The volume of one mole of a gas at standard temperature and pressure is known as the molar volume.

Thus, the correct option is 0°C and 1 atm.

Answer:

It is going to be D because Group 1 A and 2 A are s block elements which are METALS, also they are not halogens as the 7 A group is called halogens, Plus they give +1 oxidation state so Correct answer is D as they are group 1 A elements so they have only one valence electron in their valence shell

The distinctive odor of vinegar is due to acetic acid, HC₂H₃O₂, which reacts with sodium hydroxide. If a 3.45 mL sample of vinegar needs 42.5 mL of 0.115 M NaOH to be neutralized, how many grams of acetic acid are in a 1.00 L bottle of this vinegar?​

Answers

Answer:

Explanation:

CH₃COOH + NaOH = CH₃COONa + H₂O .

42.5 mL of .115 M of NaOH will contain .0425 x .115 moles of NaOH

= 48.875 x 10⁻⁴ moles NaOH

It will react with same number of moles of acetic acid

So number of moles of acetic acid in 3.45 mL = 48.875 x 10⁻⁴

number of moles of acetic acid in 1000 mL = 48.875 x 10⁻⁴ x 10³ / 3.45 moles

= 1.4167 moles

= 1.4167 x 60 gram

= 85 grams .

So 85 grams of acetic acid will be contained in one litre of acetic acid.

What colors are the fireworks in the photo? How do you
think the matter and energy of fireworks of different colors are similar and
different?

Answers

Answer:

Shortly after, the electron will fall back down to a lower energy level, releasing energy in the form of light. Therein lies the key to colorful fireworks!

The matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage.

What is Matter?

Matter may be defined as any sort of substance that is constructed of numerous types of particles that occupy physical space and possess inertia. In simple words, matter may be characterized as anything which occupies space and has mass.

When the electrons move from the ground stage to the excitatory stage, they require a significant amount of energy in any form. But when they fall back to the ground stage from the excitatory stage, they liberates energy.

The same principle is applied in the colorful observation of fireworks. The stored energy is released and different colors of fireworks become visible.

Therefore, the matter and energy of fireworks simply rely on the flow of electrons from the ground stage to the excitatory stage and vice-versa.

Answers

Strontium has an electron configuration of [Kr]5s²

Further explanation  

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

s: 2 electrons  

p: 6 electrons  

d: 10 electrons and  

f: 14 electrons  

From an electron configuration of [Kr]5s² can be concluded :

element is in period 5 (5 = shell)element is group 2(valence electron =2 and block s) has atomic number 38 (Kr = 36 + 2(valence elektron from 5s²)

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.01 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{9.01}{6.02} \\ = 1.496677740...[/tex]
